Atmospheres (2018)[edit]
If its of any use to anyone, a list of potential atmospheric gases and taints is provided below. Edit (and copy) for the coding:
Typical Atmospheric Gases
- nitrogen (N2)
- oxygen (O2)
- argon (Ar)
- water vapor (H2O)
- carbon dioxide (CO2)
- neon (Ne)
- ozone (O3)
Other Atmospheric Gases
- carbon monoxide (CO)
- sulfur dioxide (SO2)
- ammonia (azane) (NH3)
- nitrogen dioxide (NO2)
- xenon (Xe)
- radon (Rn). Radon gas is radioactive: emission rates exceed X rads per hour.
- hydrogen (H2)
- hydrogen sulfide (H2S)
- helium (He)
- methane (CH4)
- nitric oxide (NO)
- phosphine (PH3)
- hydrogen peroxide (H2O2)
- nitrogen dioxide (NO2)
- ammonium hydrosulfide ((NH4)HS)
- ammonia hydrosulfide (H5NS)
- nitrogen trichloride (trichloramine) (NCl3)
- chlorine (Cl)
- ethane (C2H6)
- acetylene (C2H2)
- diacetylene (C4H2)
- propane (C3H8)

- ammonia hydrosulfide (H5NS)
- (trace component of gas giant atmospheres)
Potential Atmospheric Taints[edit]
- the extremely high atmospheric pressure, which causes tremors, drowsiness, breathing difficulties (including oxygen toxicity) and decreased neural activity.
- the low percentage of atmospheric oxygen.
- the high percentage of atmospheric oxygen (oxygen toxicity).
- the high percentage of atmospheric carbon dioxide / carbon monoxide / sulfur dioxide / hydrogen sulfide (typically of volcanic origin).
- the high percentage of inert gases, principally argon / neon / xenon.
- trace airborne contaminants of organic origin that produce a psychological response in humans. Effects might include euphoria, mania or hallucinations, and range in severity from mild to extreme.
- an extremely unpleasant odor (floral fragrances / excrement / sulfur compounds) that triggers a gagging reflex in humans.
- large amounts of airborne silicates and dust.
- concentrations of airborne heavy metals.
- airborne radioactive dust: radiation levels exceed X rads per hour.
- the relatively high levels of background radiation: emission rates exceed X rads per hour.
- the lack of water vapor in the atmosphere.
- concentrations of airborne toxins of organic origin.
- airborne pathogens.
- allergenic spores and pollens of organic origin.
- high concentrations of chlorine and fluorine, typically of geochemical origin.
- nitrogen compounds (ammonia, nitrogen monoxide).
- pollution, current or past, typically of industrial origin
Abiotic Oxygen
- The oxygen in the atmosphere is abiotic in origin, produced by the photocatalytic reaction between the high levels of UV energy radiating from the star and titanium dioxide (TiO2), which is found in surface minerals such as ilmenite.
- Oxygen contained deep within the world's interior is released by outgassing and serves to renew the atmosphere: it continuously reacts with surface materials and other atmospheric gases, gradually reducing the percentage of oxygen in the air.
